CAIRO (AP) — A colleague of a leading investigative journalist and human rights advocate says he is facing accusations from Egypt's military prosecutor.

Lina Attalah, the chief editor of independent news website Mada Masr, says on Twitter that Hossam Bahgat told her over the phone that he has been moved to military prosecution following hours of interrogation by military intelligence Sunday. She says the accusations against Bahgat remain unclear.

Bahgat founded and directed the Egyptian Initiative for Personal Rights, a top Egyptian rights organization. He was honored with a Human Rights Watch Alison Des Forges Award in 2011.

Bahgat has recently published a series of investigative journalism reports on Mada Masr.

Egypt's government has launched a sweeping crackdown on voices opposing the government, including the Muslim Brotherhood and secular and leftist pro-democracy activists.
